Impedance Analyzer

Impedance Analyzer / Horn analyzer is mainly used for piezoelectricity element impedance analysis and parameter calculation. Before using piezoelectricity element, you need to know its major parameters: resonance frequency Fs, antiresonance frequency Fa, half point power F1 and F2, the max. admittance Gmax, direct capacitance C0, dynamic resistance (R1, C1, L1), free capacitance CT, free dielectric constant 33T,mechanical quality factor Qm, electromechanical coupling factor Keff, plane electromechanical coupling factor Kp and so on.

HS70A (Improved) Impedance Analyzer(1KHz~500KHz)Including:
Clip lead, Mains lead (220V/110V, 50/60 Hz), RS232 Lead, USB2. 0 to RS232 cable,
Ceramic-specific clipper, PiezoView PC Software(English), User Manual(English), Calibration Certificate

This instrument can measure admittance characteristic curve of piezoelectricity element (the admittance is equal to reciprocal of impedance) and analyze and extractthe above needed parameters. With this instrument, you can gain four characteristic curves of piezoelectricity element (admittance characteristic graph, impedancecharacteristic graph, admittance coordinate graph, impedance coordinate graph).
Moreover, it is easy to save and print the measured result.

This instrument combines the hardware and PC software for impedance analysis. The hardware system finishes impedance measure, and the PC software finishes impedance analysis and parameter extraction power.

This instrument is used for guiding piezoelectricity element’s testing and using.It is a synthetic solution of piezoelectricity element’s measurement and analysis.Moreover, it can evaluate and test parameters of the piezoelectricity element.

Impedance analyzer is widely applied in ultrasonic industries,including ultrasonic plastic welder, ultrasonic cleaner, ultrasonic transducer,ultrasonic electro machining, underwater acoustic transducer, ultrasonic sensor, piezoelectric ceramic, parking sensor, medical ultrasonic device, ultrasonic scaling device, ultrasonic horn, ultrasonic welding head, ultrasonic grinder, and ultrasonic emulsor.

Impedance analyzer is adopted to help the company make much profit, for more info visit

How to Clean Outdoor Hiking Backpack?

How to Clean Outdoor Hiking Backpack, here are five steps to clean
Step 1
If you notice a stain, food spill or plant matter (like tree sap or berry stain) on your backpack, wipe it off immediately with a damp cloth (and mild antibacterial soap or detergent if you have some with you). This will prevent staining and will also prevent buildup, which can draw ants and other bugs and cause the material to wear through.
Step 2
When you’re home, give the pack a thorough cleaning (but only when you know there’ll be a few days between your hiking trips). Remove the detachable pockets and clean them separately from the main pack. Brush off or vacuum the pack outside and inside to remove dust, dirt, rocks, sticks and debris. Wipe down the outside and inside with a damp cloth, using mild soap or detergent that is chemical- and dye-free. The chemicals and dyes in traditional soaps can wear through the layers of waterproofing on your pack and increase the chances of rips and tears in the material.
Step 3
To clean corners, use an old toothbrush to scrape out debris, and remember to check between the fabric and the frame for dirt and dust. For zippers, trim all excess threads and remove debris with an old toothbrush. (It doesn’t hurt to use a small amount of silicone spray on the zippers each time you clean your pack to keep them lubricated and prevent rusting or sticking.)
Step 4
Once you’ve cleaned both inside and out, rinse off all traces of soap. You can do this by submerging the pack briefly in a bathtub filled with cold water, but it’s easier on the material and on you to hose it out with a detachable showerhead or a garden hose. Make sure all suds are out and that no soap has built up in corners or small pockets. Hang the pack upside down to dry in a cool, dark area. Hanging it up outside on the line is best, particularly if you can avoid direct sunlight; indoor drying will work if the area is well-ventilated. A circulating or ceiling fan will speed up the drying process, but at least 2 to 3 days of drying is recommended. If smell persists, use a backpack-safe spray that won’t eat away the laminate on the material to freshen it up.
Step 5
It is possible to wash a backpack in the washing machine, but it is certainly not recommended and should be used only as a last resort in cases of mildew, mold or old, smelly food stains. If you’ve tried all the steps above and still feel the pack needs to be washed more thoroughly, you can try the washing machine, but there’s no guarantee it won’t ruin your materials, clasps and attached elements, forcing you to buy a new pack anyway. If using the washer, never soak the pack in soapy water. This can cause holes and tearing in the material. Clean out all debris from corners and seams and remove the frame, all metal stays and detachable pockets. Wash on the delicate cycle in cold water only, and only use a mild or chemical-free detergent. Never tumble dry the pack–always place upside down to drip-dry in a well-ventilated, cool area.
